[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for permeating rainwater into the ground through a waterway such as a gutter.

[0002]

2. Description of the Related Art Conventionally, various structures have been proposed as rainwater permeation structures for permeating rainwater into the ground through gutters. In the conventional one, a filter is installed at an appropriate place so that the soil and dust contained in rainwater do not cause clogging at the outflow portion into the ground, and this filter filters rainwater to remove soil and dust. After removing it,
This filter is designed to penetrate into the ground.
As time passes, it gradually becomes clogged and the filtration function deteriorates, so this must be replaced.

[0003]

However, in the conventional rainwater infiltration structure, when the filter is clogged and needs to be replaced, the filter cannot be easily attached and detached, and it takes a lot of time and effort to replace the filter. There was a problem that it was poor in practicality.

Focusing on the above-mentioned conventional problems, the present invention provides a rainwater permeation structure for a water channel, which is capable of sufficiently filtering rainwater by a filter and being easily attached and detached when the filter is replaced. The challenge is to provide.

The water guiding member is provided therein with a laterally extending portion extending laterally from the opening, and a withdrawing member detachable from the inside of the water channel through the opening is provided in the laterally extending portion. The drawing member has a filter attached thereto.

[0006]

In the rainwater permeation structure for a water channel of the present invention, rainwater flowing in the water channel flows into the inside of the water guiding member from the opening, and the rainwater flowing into the water guiding member is filtered by the filter to the underground. Permeates into.

[0007] As described above, since dust, earth and sand, etc. contained in rainwater are removed by the filter, the outflow portion from the water guiding member to the ground does not become clogged with earth and sand and the rainwater to the earth Can maintain its permeability.

In order to sufficiently carry out filtration with a filter, it is desirable to dispose the filter at a plurality of locations inside the water-conducting member or to form the filter thickly. If it is arranged or formed thick, it is necessary to provide a space for installing the filter in the water guiding member, and when the filter is installed there, it is necessary to easily replace the filter.

In this case, in the present invention, since the lateral portion is formed on the water guiding member and the lateral portion is used as the installation space for the filter, the filter can be arranged at a plurality of places or formed thick. Therefore, the filtration with the filter can be sufficiently performed.

Further, since the drawing member is detachably provided inside the lateral portion and the filter is attached to the drawing member, if the drawing frame is drawn out from the water guiding member through the opening from the inside of the water channel, only by itself, at the same time. The filter can be taken out and the filter can be easily replaced.
